To all wlwm it may concern:

Be it known that I, LOUIS A. Sonnorr, a citizen of the United States,.residin at Chicago, in the county of Cook and tate of Illinois, haveinvented certain new and useful Improvements in Methods of Making SpringAssemblies for-Upholstery; and do hereby declare the following to be afull, clear, and exact descri tion of the invention,

such as will enable 0t lers skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in methods of constructing springassemblies for upholstery purposes, including seat cushions and backsand sides for furniture, automotive vehicles, railway cars and the likeand has for its particular object to provide a method whereby, duringfabrication of one part of the structure an interengagement thereof withthe other is effected which is permanent and of such a nature as toprovide great strength and durability in the completed articleandwhereby a very considable saving in labor and materials is efiected.

The several steps of the method are fully illustrated in theaccompanying drawings wherein 7 o I Figure 1 is an lnverted perspectivevlew of a fabric structure constituting a part of the finished productresulting from carrying outthe method of the invention;

Fig. 2 is a view similar to Fig. 1 showing parts of .the metallic baseassociated with portions of the fabric structure;

Fig. 3 is a perspective view of the completed structure with theexception that only a few of the cells or pockets thereof are shown tocontain springs.

The present application is a divlsion of my application, Serial No.21,816, filed April 9, 1925, for improvements in spring assemblies forupholstery, which, as originally filed, described and claims saidproduct and the method of making the same.

In carrying out the method aforesaid, there is first constructed afabric housing comprising a top wall or cover '1, a pair of side walls 2and a pair of end walls 3, all of the latter being joined along theirupper edges with the top wall 1 in any suitable manner. One end wall 3is secured along its side edges to the contiguous ends of the side walls2.

Prior to securing said end .wall 3 to the side walls 2, the longitudinalpartition walls 4 are secured to the top wall by lines of stitching 5,the said partition walls being provided along their free edges with hems6 before being secured to the top wall 1.

Narrow transverse partition walls 7, similarly provided with hems 8, aresecured by -lines of stitching to the'top wall 1, the relativearrangement of the side and end walls 2 and 3 and the partition-walls 4and 7 being such that when said several walls are disposedperpendicularly to the top wall they will border substantially squarepockets or 1 cells of uniform size.

A rectangular 'or substantially rectangular border wire frame 9 (Fig. 3)is then secured preferably by stitching to the free edges of one end an.two side walls of the structure. Intermediate wires 10 are then passedthrough the hems 6 of the partition walls 4., said wires being of suchlength that they project over diametrically opposed portions oftheborder wire frame 10 about which they are looped as shown in Fig. 3.

Wires 11 which, preferably, are crimped at regularly spaced intervals,equal substantially to the diameter of the cells or pockets formed bythe peripheral and partition walls, are passed through the hems 8 of thepartition walls 7 and, at their ends, are looped about the border wireframe, the crimps or bends 12 of the wires 11 being disposed at thepoints of intersection or crossing of said wires 11 with the wires 10.

The structure now presents a flexible fabric superstructure interlacedwith a skele ton wire base, the wires of the latter maintaining the freeends of the peripheral and partition Walls in the same or substantiallythe same relative positions as the other ends thereof which are attachedto the top or cover fabric 1, thereby providing pockets or cells toreceive coiled springs 13. But the wires 10 and 11 are not of suflicientcrosssectional dimensions to properly support the springs 13 so that theadditional light supporting wires 14: must be provided. These areinserted transversely through the heme 6 and 8 respectively in staggeredrelation to the wires 10 and 11 and just above 0;

inwardly of the latter so as to bridge the mouths of the pockets orcells. I

' After the wires14 have been inserted and before the still detached endwall 3 of the structure is joined along its still free three edges tothe side Walls 2 and the border wire frame 9, the springs 13 areintroduced in collapsed condition into the several cells or pocketsthrough the narrow slits or slots means of the tool shown and describedinme Letters Patent No. 1,352,157 grantedto on the 7th day of September,1920.

the best' manner of carrying out the inven .tion to produce the best andmost economical structure exemplified in the drawings but the inventionis not limited to the production'of the precise structure illustratednor.-

to the exact sequence or nature of said steps as the latter may bechanged and varied to a considerable extent to produce the structureillustrated or modifications thereof without departing from theinvention asdefined in and-by the appended claims.

I claim as my" invention:

1. The method of making spring assemblies which consists in constructinga fabric structure presenting a series of pockets or cells adapted tocontain coiled springs, and fabricating a foraminous wire base for oneend of said structure by successively interlacing certain of the severalcomponent elements of the base with walls of the pockets of said fabricstructure and then securing all of the component elements of said baseagainst displacement relatively to each other, and inserting springs.

building a fabric superstructure presenting a series of cells or pocketsadapted to receive. and confine springs, fabricating a foraminous Wirebase forthe bottom of said superstructure by successively permanently connecting several of the component. parts vof said base with walls ofsaid cells or pockets, and thereafter permanently congnecting all of thecomponent parts of said base witheach other, and inserting springs intosaid pockets orcells.

3. The method of making spring assemblies which consists Pin the severalsteps of "constructing a fabric superstructure presenting pockets forcontaining springs, constructing a substantially rigid skeleton baseincluding relatively intersecting spacing p -.-;bars by successivelyconnecting the latter The foregoing description is directed to said basein spaced relation to each other to thereby permanently maintain thewalls of said pockets in spaced relation to each pockets.

4.-The method of making spring assemblies which consists in the severalsteps of constructing a fabric superstructure presenting pockets forcontaining springs, constructing a substantially rigid skeleton baseincluding relatively intersecting spacing bars by successivelyconnecting the latter with the walls of said cells or pockets andsecuring all of the component .elements of said base in spaced relationto each other to thereby permanently maintain the walls of said pocketsin spaced relation to each other, connecting spring supporting elementswith said spacing bars and the walls of said pockets. and insertingsprings into said pockets.
